Sobolev's original proof of the Sobolev embedding theorem relied on the following, sometimes known as the Hardy–Littlewood–Sobolev fractional integration theorem. An equivalent statement is known as the Sobolev lemma in (Aubin 1982, Chapter 2). A proof is in (Stein, Chapter V, §1.3) harv error: no target: CITEREFStein (help). Let 0 < α < n and 1 < p < q < ∞. Let Iα = (−Δ) be the Riesz potential on R . Then, for q defined by WebOct 20, 1999 · Optimal constants are found in Hardy–Rellich inequalities containing derivatives of arbitrary (not necessarily integer) order l. Some new inequalities of this type are also obtained. ... Sharp constants in the Hardy–Littlewood–Sobolev and related inequalities. Ann. of Math., 118 (1983), pp. 349-374. CrossRef Google Scholar. 9.

WebApr 3, 2014 · This work focuses on an improved fractional Sobolev inequality with a remainder term involving the Hardy-Littlewood-Sobolev inequality which has been proved recently. By extending a recent result on the standard Laplacian to the fractional case, we offer a new, simpler proof and provide new estimates on the best constant involved. … WebIn mathematical analysis, the Hardy–Littlewood inequality, named after G.
